Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, and it should be understood that the preferred embodiments described below are only for the purpose of illustrating and explaining the present invention, and are not to be construed as limiting the present invention.
Fig. 1 is a schematic flowchart of an automatic control method for off-peak startup of a computer cluster according to an embodiment of the present invention, and as shown in fig. 1, the method may include:
step S101: each computer in the computer cluster acquires a first command for generating a timing startup time parameter and a second command for writing the timing startup time parameter into a BIOS (basic input output System) from a network side server;
step S102: each computer generates a timing startup time parameter according to the first command, so that the next timing startup time of all computers of the computer cluster is uniformly distributed in a preset time period;
step S103: each computer writes the generated timing startup time parameter into a BIOS according to the second command;
step S104: and after each computer is shut down, when the next time of the timed startup time is determined to be reached according to the timed startup time parameter written in the BIOS, automatically executing a startup process so as to start all the computers of the computer cluster by mistake.
In practical applications, the computers in the computer cluster may execute the above steps S101 to S103 after acquiring the notification message that needs to be maintained by the network side server. The computers in the computer cluster may also send requests to the network side server periodically or periodically to query whether the network side server sends out the computer cluster maintenance requirement, and if it is determined that the network side server sends out the computer cluster maintenance requirement, the above steps S101 to S103 are performed.
In order to implement peak-off startup of the computers, the embodiment generates the timing startup time parameter by using at least one of random information and unique information in the system of each computer, for example, integer seconds and decimal seconds in the system time, and the IP address and the MAC address of the computer. At this time, step S102 may specifically be: and each computer in the computer cluster acquires at least one of the system time and the identification address of the computer according to the first command, and generates a timing startup time parameter according to at least one of the system time and the identification address of the computer.
The embodiment is intended to finish off-peak startup in a time period when a user does not use the computer, and run the automatic script set in the startup item to automatically realize the maintenance operation of the computer. To achieve this, during the execution of the above steps S101 to S103, the method may further include the following steps as shown in fig. 2:
step S201: each computer in the computer cluster acquires an automation script for maintaining the computer and a fourth command for writing the automation script into a startup item from a network side server;
step S202: and each computer writes the automatic script into the startup item according to the fourth command, so that the automatic script written into the startup item is executed in the automatic startup process, and the maintenance operation of the computer is realized.
In practical applications, since the timed booting time parameter is written into the BIOS in step S103, the computer will automatically boot up whenever the timed booting time is reached. Since the computer cluster does not need to be automatically powered on after the maintenance operation of the computer is completed, the timed power-on function of the computer should be turned off after the maintenance operation of the computer is completed. To achieve this, the present embodiment adds a third command to the automation script to turn off the timed on function. In a specific implementation, each computer in the computer cluster may obtain the third command carried by the computer cluster through an automation script, that is, the automation script obtained from the network-side server has a third command for turning off the timed on-off function, or, during the execution of the above steps S101 to S103, each computer in the computer cluster obtains the third command for turning off the timed on-off function from the network-side server and adds the third command obtained from the network-side server to the automation script, so that the third command may be executed during the execution of the automation script. Specifically, the method may further include the following steps as shown in fig. 3:
step S105: in the automatic starting process of each computer in the computer cluster, executing the automatic script written with the starting item to realize the maintenance operation of the computer;
step S106: after the automatic script is used for realizing the maintenance operation of the computers, each computer in the computer cluster closes the timing starting function according to the third command in the automatic script, so that each computer is prevented from automatically executing the starting process again according to the timing starting time parameter written in the BIOS;
step S107: and after the timing startup function of each computer is closed, deleting the automatic script and executing a shutdown process.
And after all the computers of the computer cluster finish the operation, finishing the automatic maintenance process of the computer cluster.
It should be noted that the computers of the computer cluster may acquire and execute at least one of the first to fourth commands during the period of being used by the user, or may acquire and execute at least one of the first to fourth commands during the period of executing the shutdown script when the user clicks the shutdown.
The embodiment of the invention also provides a computer readable medium, on which an automatic control program for peak-off startup of a computer cluster is stored, and when the automatic control program for peak-off startup of the computer cluster is executed by a processor, the steps of the automatic control method for peak-off startup of the computer cluster are realized. That is, one of ordinary skill in the art will appreciate that all or some of the steps of the methods, systems, functional modules/units in the devices disclosed above may be implemented as software, firmware, hardware, and suitable combinations thereof.

Some or all of the physical components may be implemented as software executed by a processor, such as a central processing unit, digital signal processor, or microprocessor, or as hardware, or as an integrated circuit, such as an application specific integrated circuit. Such software may be distributed on computer readable media, which may include computer storage media (or non-transitory media) and communication media (or transitory media). The term computer storage media includes volatile and nonvolatile, removable and non-removable media implemented in any method or technology for storage of information such as computer readable instructions, data structures, program modules or other data, as is well known to those of ordinary skill in the art.

In addition, communication media typically embodies computer readable instructions, data structures, program modules or other data in a modulated data signal such as a carrier wave or other transport mechanism and includes any information delivery media as known to those skilled in the art.
The following 2 schemes are mainly used as practical startup control techniques for enterprise computers, and for computers meeting certain technical requirements, the computers can be controlled to be automatically started up in a state of being shut down and keeping power on (the power on state is a necessary condition, and will not be described repeatedly below). (1) The wake-on-lan technique is to send a specific data packet (or magic packet) to a target computer through a network. The technology firstly requires corresponding parameter setting on a series of links such as a computer BIOS, a network card driving program, an operating system, each level of network switch and the like, so that the magic packet can be guaranteed to be sent to a target computer through a network, and the target computer responds after receiving the magic packet and is automatically started in a correct mode. Some models of computers must even refresh the BIOS to a specific version to effectively support wake-on-LAN. Secondly, the MAC address of the network card of each target computer needs to be accurately grasped as the target address for sending the magic packet. Finally, IT personnel must specially write a timing sending program, send magic packets to all target MAC addresses in the network in batches and at a fixed time, and then achieve the goal of controlling the target computer to start up at a wrong peak. Therefore, the network awakening technology is very complex and the realization difficulty is very high. (2) The timed startup technology is to start the timed startup function in the BIOS of the target computer and set the startup time. The technology is generally supported on a PC and is relatively simple to implement. Setting a starting time in the BIOS of the target computer, and automatically starting up the target computer when the set starting time is reached after the target computer is turned off. And (4) setting the disable in the BIOS to close the timed startup function. Since the IT department of an enterprise usually sets the BIOS manually, IT is obviously infeasible to rely on manual operation to perform timed boot control on thousands of computer clusters.
Therefore, the invention is based on the timing startup technology, and realizes the automatic control of the off-peak startup of the enterprise computer cluster very simply and conveniently by compiling the randomly generated startup time parameter and automatically setting the control command of the BIOS and matching with the automatic script for IT maintenance, thereby ensuring that the IT automatic maintenance is completed safely and efficiently. To achieve the above object, the embodiments of the present invention should include at least the following steps:
1. and selecting a peak-off starting time period.
The purpose of off-peak startup is to avoid the time period of centralized startup of the computer cluster and avoid executing the automation scripts at the same time.
(1) The optimal choice for the off-peak boot-up period is the night off-time period.
The automatic script is designed to delete itself and automatically shut down after the execution is finished in the off-peak startup time period, and no automatic script is started after the staff goes on duty and starts up. Namely, all automatic maintenance operations are completed within the selected night off-peak startup time period.
(2) The non-working time is fully utilized, the peak-staggering starting time period (such as 0: 00-5: 00) is properly prolonged, the starting time of all the computers is controlled to be uniformly distributed in the time period, the number of the computers which are started at any time is reduced, the network load is balanced and not overloaded, and the loss is minimum when an unexpected power failure or network disconnection accident occurs.
2. And generating a starting time parameter.
The BIOS boot time parameter is required to provide "hours" and "minutes" values. For example, the power-on time is set to be 2:30, and the computer is automatically powered on when the time reaches 2:30 after being powered off. The simplest method is to use some of the variables in the target computer system that are unique (e.g., IP address) or random (e.g., system time) to automatically generate the boot-time parameter. Taking the capture system time "seconds" value as an example, as shown in fig. 4, the system time "seconds" values of 1432 computers are substantially evenly distributed. That is, the system time of each computer is not completely synchronized at the "second" level, so that the system time is captured at any time on any computer, and the "second" value is taken as a random variable. Because the value ranges of the second and the minute are the same (0-59), the value of the second can be directly defined as the value of the minute in the starting time. By analogy, the randomly generated boot time on each target computer will be uniformly distributed within the whole off-peak boot time period.
In this embodiment, a group of program commands for generating the timed boot time parameter is referred to as command 1 (or first command). Command 1 generates evenly distributed boot time points, which are the basis for off-peak boot.
3. The BIOS utility is invoked.
The enterprise computer cluster generally takes a commercial brand computer as a main part and generally supports a timing starting technology. Computer vendors may provide proprietary BIOS utility software for free to read, set, or modify BIOS parameters. According to the command parameter format given by the software use description, the BIOS tool software is called, so that the time parameter of the timed startup can be written into the target computer BIOS (command 2, or called as a second command), and the BIOS can be set to close the timed startup function (command 3, or called as a third command). Thus, the problem of setting up the BIOS is solved in a manner that program commands are executed.
It should be noted that the command 2 is automatically written into the BIOS boot time parameter, which is an implementation means of off-peak boot automatic control, and the command 2 implies a start-up timing boot function, for example, a certain time point of each day for timing boot.
It should be noted that the command 3 is a command for setting the timed boot function in the BIOS, and the timed boot function selects a certain time point of the evenyday, and after the timed boot is successful (meaning auto-boot- > execute the automation script- > complete the maintenance task), the timed boot is not required every day any more. Therefore, the timed power-on function should be turned off in the automation script.
4. The automation script is configured.
The automation script contains all maintenance operation commands for the computer. And adding a command 3 in the automation script, and setting a BIOS to close the timed startup function after the automation maintenance is finished. At the end of the automation script, a shutdown command and a command for deleting the automation script should be set, so that the computer is automatically shut down after all maintenance operations are finished, and the automation script is not started again after the computer is restarted.
In this embodiment, a command for copying the automation script to the boot entry of the target computer is written, which is called command 4 (or called fourth command). The automation script is stored in a network side server and is accessed by all target computers.
In this embodiment, command 4 is written into the shutdown script, and the automation script is intended to be set to automatically start up every time the computer is shut down, and the next time the computer is started up.
It should be noted that the shutdown script, the shutdown script policy, and the command 4 related to this embodiment are used to explain the entire automation operation process.
As shown in fig. 5, after the target computer is powered on and self-started, the automation script is used to complete the automation maintenance, then the command 3 is executed, the BIOS is set to close the timing power-on function, and finally the command of the power-off command and the command of deleting the automation script are executed.
5. And (5) preparing the process.
The command 1, the command 2 and the command 4 need to be executed on the target computer, and preparation work for setting the regular startup time of the BIOS and starting the automatic script after startup is well done. These commands should likewise be automatically executed on the target computer by technical means.
For example, a shutdown script management policy that enables the target computer may be included, but is not limited to. Command 1, command 2, and command 4 are written in sequence in the shutdown script. When the employee clicks 'shutdown' to the target computer, the operating system first triggers a shutdown script at the background, and executes each command in sequence to automatically complete the preparation work. After the shutdown script is executed, the operating system sends a physical shutdown signal to the motherboard.
The automatic control of the computer cluster off-peak startup can be implemented by combining with the automatic maintenance process of the enterprise IT, as shown in fig. 6, the specific implementation process is as follows:
step S301: automation script add command 3.
The automation script contains all maintenance operation commands. And adding a command 3 in the automation script and setting a BIOS closing timing shutdown function. At the end of the automation script, a shutdown command and a command for deleting the script should be set, so that the computer is automatically shut down after all maintenance operations are finished, and the automation script is not started again.
Step S302: command 1, Command 2, and Command 4 are executed on the target computer.
And randomly generating a timing startup time parameter on the target computer and writing the timing startup time parameter into the BIOS to finish the preparation work of timing startup and starting the automatic script.
Step S303: and the staff is shut down after work.
Step S304: and when the starting time is reached, the machine is automatically started.
Step S305: and starting an automation script and automatically executing all maintenance operations.
Step S306: and automatically shutting down.
The set of boot-time parameters generated from executing command 1 on each target computer, as seen from the computer cluster as a whole, are uniformly distributed within the planned off-peak boot-time period due to randomness.
After the employee is shut down from work, all the target computers are automatically started in sequence at the starting time points set by the BIOS of the target computers along with the time entering the off-peak starting time period, the automatic script is started, and the automatic maintenance operation is executed. When the command 3 is executed, the timed starting function is automatically closed. When the last computer cluster is shut down, the whole off-peak startup automatic control and automatic maintenance operation process is completed.
It should be noted that, the shutdown script is stored in the target computer, for example, after a "shutdown script policy" of a Windows is started, when a user clicks "shutdown", the operating system first executes the local shutdown script, and then actually shuts down (i.e., physically shuts down).
Examples of the applications
Upgrading an application system of a Client/Server (C/S) architecture is a common scenario in enterprise IT maintenance. When the server side is upgraded from the old version to the new version, the client side of the old version cannot work due to incompatibility, and the server side can be recovered to be normal only after the client side is also upgraded to the new version. According to the traditional upgrading mode, no matter manual operation or script execution, thousands of computer clusters need a long time period to complete upgrading work, most computers cannot use the application system in nearly the whole period, and the daily work of an enterprise is undoubtedly influenced negatively, as shown in fig. 7 a. If the off-peak startup automatic control scheme provided by the invention is adopted and the automatic script is executed, all the clients and the server can be ensured to complete synchronous upgrade in the same day, and uninterrupted switching of service application is really realized, as shown in fig. 7 b.
Fig. 8 is a schematic structural block diagram of an automatic control system for off-peak startup of a computer cluster according to an embodiment of the present invention, and as shown in fig. 8, the system may be applied to each computer of the computer cluster, and the system may include:
a command obtaining module 10, configured to enable each computer in the computer cluster to obtain, from a network-side server, a first command for generating a timed startup time parameter and a second command for writing the timed startup time parameter into the BIOS;
the parameter generating module 20 is configured to generate a timing startup time parameter of each computer according to the first command acquired by each computer, so that the next timing startup time of all the computers of the computer cluster is uniformly distributed in a preset time period;
a write-in module 30, configured to write the generated timed boot time parameter into the BIOS according to the second command acquired by each computer;
and the automatic starting module 40 is used for automatically executing the starting process when the next time of the timed starting time is determined to be reached according to the timed starting time parameter written in the BIOS after each computer is shut down, so that all computers of the computer cluster are started in a peak-off manner.
In practical application, the computers in the computer cluster can perform command acquisition and execution after acquiring the notification message which is sent by the network side server and needs to perform computer maintenance. The computers in the computer cluster can also send requests to the network side server periodically or periodically to inquire whether the network side server sends out the computer cluster maintenance requirements or not, and if the network side server is determined to send out the computer cluster maintenance requirements, command acquisition and execution are carried out.
In order to implement peak-off startup of the computers, the embodiment generates the timing startup time parameter by using at least one of random information and unique information in the system of each computer, for example, integer seconds and decimal seconds in the system time, and the IP address and the MAC address of the computer. At this time, the parameter generating module 20 may be specifically configured to obtain at least one of the system time and the identification address of the self according to the first command, and generate the timed boot time parameter according to at least one of the system time and the identification address of the self.
The embodiment is intended to finish off-peak startup in a time period when a user does not use the computer, and run the automatic script set in the startup item to automatically realize the maintenance operation of the computer. To achieve the purpose, the command obtaining module 10 may be further configured to enable each computer in the computer cluster to obtain, from the network-side server, an automation script for performing maintenance operation on the computer and a fourth command for writing the automation script into a boot start item; the writing module 30 may also be configured to write the automation script into the boot entry according to the fourth command acquired by each computer, so that in the process of automatically executing boot, the automation script written into the boot entry is executed, and thus, the maintenance operation on the computer is implemented.
In practical applications, since the write module 30 has written the timed booting time parameter into the BIOS, the computer will automatically boot up whenever the timed booting time is reached. Since the computer cluster does not need to be automatically powered on after the maintenance operation of the computer is completed, the timed power-on function of the computer should be turned off after the maintenance operation of the computer is completed. To achieve this, the present embodiment adds a third command to the automation script to turn off the timed on function. In a specific implementation, the command obtaining module 10 may obtain the third command carried by the automation script through the automation script, that is, the automation script obtained by the command obtaining module 10 from the network-side server has a third command for turning off the timed on-off function, or during obtaining and executing the first and second commands, the command obtaining module 10 obtains the third command for turning off the timed on-off function from the network-side server and adds the third command obtained from the network-side server to the automation script, so that the third command may be executed during executing the automation script. Specifically, the auto-boot module 40 of the system may be further configured to execute an automation script written with a boot entry in an auto-boot process, to implement a maintenance operation on the computer, and after the maintenance operation on the computer is implemented by using the automation script, close the timed boot function according to the third command in the automation script, so as to prevent each computer from automatically executing the boot process again according to the timed boot time parameter written with the BIOS, and then delete the automation script and execute the shutdown process after closing the timed boot function.
On the basis of having possessed the automation script that can replace manual operation already, adopt the off-peak start-up scheme that this embodiment described, can make automation mechanized operations accomplish more safely high-efficiently.
In summary, the embodiments of the present invention have the following technical effects:
